Instructions
#1 |
| |
 |
This projector is
fairly simple to build and should take around 1 hour to complete. It works great
and looks nice when completed.
You can paint the final product any color or you can leave
it unpainted. We recommend Silver or Black. | |

Materials
Needed |
| |
|
|
You will need basic household tools to complete this
project
- Your existing TV. (A 14" Flat screen TV is shown)
- The Fresnel Lens that was mailed to you.
- Duct Tape or similar strength tape.
- Razor Knife, Scissors, or a sharp kitchen knife. (to cut
the cardboard)
- Pencil or Pen.
- Ruler, or tape measure.
- Straight edge, ruler, or square. (To cut on a straight
line)
- Cardboard. (Thin plywood can be used instead of
cardboard)
- Black Spray Paint.

Step
#1 |
| |
|
|
Take a tape measure or ruler and measure the
outer length and width of your TV. Not the screen size, but the entire
TV. |
| |
 |
|
Step
#2 |
|
|
|
Now you will cut four sides to construct the
outer box. First mark out on your cardboard or wood the TV Width of 18". Then
mark out one with the TV height of 18"(note your dimensions may be different
depending on your TV size). Cut one of each (width and height) and use them as a
pattern to cut out the other two. Use the diagrams for a visual
aid. |

You can spray paint the inner sides
of your cardboard black for a better picture
(optional)
-
Now you will take the four pieces from step two
to create the outer box (top, bottom, left, and right)
-
Tape each seem with one long piece of duct tape
as shown.
-
Picture #1 - Shows a 3D
diagram of the constructed and taped outer box. The thick black lines represent
were the tape goes.
-
Picture #2 - Lay the
tape out flat on the floor in front of the edge of your piece of
cardboard.
-
Picture #3 - Lift the
cardboard up, set it down covering half of the tape. Make sure the tape sticks all down the entire cardboard.
-
Picture #4 - Shows the
seem with two pieces of cardboard. Make sure it's a tight seem by placing the
cardboard edges snug against each other. The pull the tape up while you stick it
on the second piece of cardboard, thus making a very tight seem.
-
Picture #5 - Shows the
completed box where all four seems are taped.
Tip: Place tape along
both the inner and outer edges of the seem to make a stronger
box!

You can spray paint the inner sides
of your cardboard black for a better picture
(optional)
Now we will make the inner box (focusing box).
The inner box will be almost identical to the outer except slightly smaller and
will fit inside the outer box snugly.
-
Picture #1 & 2 -
Cut two pieces 15" in depth by the width of your TV minus 1/4" (This is so I can
fit inside the outer box).
-
Picture #1 & 2 -
Now cut two pieces 15" in depth by the height of your TV minus 1/4".
-
Picture #1 & 3 - We
will also cut a front piece which is the width of your TV by the height of your
TV.
-
Picture #3 - Once you
cut the front piece, you will need to cut the center hole which will be covered
by the lens. Trace from the corners using a ruler (Red Lines) to locate the
center. Then place the provided magnifying lens in the center of the cardboard
and trace around it using a pen or pencil (dotted lines). Now trace out a square
1/4" smaller on each side from the dotted line (center solid line). This is so
the center cut out is slightly smaller than the lens size. The center cutout
will be approx. 6.5" in height by 9.5" in width. Cut out the center of the
cardboard using this line.
-
Picture #4 - Now we
will mount the lens on the front cutout. Mount it on the outside of the
cardboard (side away from TV) using duct tape. Make sure the smooth side faces
away from your TV and the rigid side toward your TV.
-
Picture #5 & 6 -
Now we will finish constructing our inner box using all five sides (four side
pieces and one front piece). Construct it using duct tape just as you did on the
outer box. It will look exactly the same as the outer box except it will have a
front piece and be slightly smaller. |

Step
#5 |
|

 |
|
Now we will place the inner box inside of the
outer box and we are about ready to start viewing!
-
This step is pretty straight forward. Simply
slide the inner box inside the outer box as shown and place your TV in the back.
It should all fit snugly.
-
Now to focus it, you will slide the inner box
closer or further from your TV depending on your situation.
-
Unless you have a professional switch the picture
yoke (see troubleshooting), you will have to flip your TV upside
down. If done carefully, it will not damage your TV. If discoloration occurs,
consult the troubleshooting guide. |

 |
|
Step #6
(optional) |
|
|
|
You can now spray
paint your projector box to make it more visually appealing. Here I spray
painted it using a "Chrome" spray paint. It gives it a really nice metal flake
metallic sparkly appearance. This of course it totally optional and can be
painted any color. |

Focusing Your
Projector |
| |
To focus your projector start within one foot of your wall
or screen. Slowly move the entire works away from your wall. Typically 4-10 feet
from your wall is used for best viewing. Remember try small adjustments to
clearly focus your projector. |

Don't Want to Turn your
TV upside down?
Would you rather not turn your TV upside down? Then try this
simple method. It's called Tube Yoke Flipping. Simply find a plug with 4 wires (red - blue and yellow - green) and switch the red with the blue/blue with red and yellow with
green/green with yellow. Use the picture below for help when asking your local
TV repairman to complete this for you.

It takes five minutes and you do not have to have any
technical experience to do this! Never opened a TV before? Don't worry! Try
this, it's simple and will not damage your TV.
DO NOT OPEN YOUR TV YOURSELF!!! HAVE A TRAINED TV
PROFESSIONAL DO THIS FOR YOU!!! TV'S STORE ENERGY EVEN WHEN UNPLUGGED AND YOU
CAN BE SEVERELY ELECTROCUTED IF YOU TOUCH THE WRONG THING!!! TAKE YOUR TV TO
YOUR LOCAL TV REPAIR SHOP AND THEY CAN COMPLETE THIS FOR YOU FOR ONLY A FEW
$$.
AGAIN WE RECOMMEND YOU NOT OPEN YOUR TV YOURSELF! DO
NOT TRY IT! IF YOU DO, IT IS AT YOUR OWN RISK!
Troubleshooting
To fix the wording or text on
your projection from being backward, use the following picture.
Lay the TV on it's back, so the screen faces
the ceiling. With the projector attached to your TV, it will project to the
ceiling in this position. Now, take a mirror at a 45 degree angle and attach it
to the front of your projector box like in the above picture. This will then
redirect the projection onto your wall with the text properly displayed.
To Improve Picture
Quality:
Good results may be obtained by using a white
sheet, a light colored wall, or even a shower curtain. But for best results we
recommend you use a Silver Finished Screen made only for projected TV images.
This will give you up to 6 - times brighter pictures than any other screen or
material. No hot spots. No blurry edges. Can be viewed in partially lighted
rooms. HOW TO MAKE YOUR OWN PROJECTOR SCREEN. Simply buy from
your local paint store (for about $2.00) a Spray can of either No. 1246 Testors
Enamel in Metallic Silver, or No. 1401 Krylon Bright Silver enamel. Spray
lightly several coats on wall, ceiling, plywood, wallboard, cardboard, etc. Let
dry, and make more applications until a thick and smooth even coat of silver is
deposited. This will give you a professional viewing screen that will greatly
improve your projected TV image.
Blurry edges? Try sandwiching the lens in between
two panels of flat glass. This will insure the lens is completely flat and thus
project a better picture!
Color Problems When you
Turn your TV Upside Down?
When you flip your TV upside down, do you
get some discoloration? Try this method to fix any discoloration...
